The holding part 120 includes an upper side holding member 130 connected to the upper side connection member 170, and a palm side holding member 140 connected to the palm side connection member 180.

  The instep side holding member 130 and the palm side holding member 140 are constituted by strip-like members having flexibility. The instep side holding member 130 and the palm side holding member 140 are wound around the patient's wrist A so as to make one round while being relatively movable with respect to the patient's wrist A. The instep side holding member 130 and the palm side holding member 140 are attached to the patient's wrist A side rather than the attachment portion 110. As shown in FIG. 1, in this embodiment, the palm-side holding member 140 is mounted on the patient's central side (lower side in FIG. 1) than the back-side holding member 130. This is because, as will be described later, the palm-side holding member 140 may be moved more centrally and fixed in a state where the shape of the hand H is maintained in a desired shape.

  The instep side holding member 130 and the palm side holding member 140 are configured to be relatively close to and away from the mounting portion 110 by moving relative to the patient's wrist A. Further, the upper side holding member 130 and the palm side holding member 140 are surfaces facing the body surface of the hand H and the body surface of the hand H to such an extent that the state can be held at a predetermined position of the patient's wrist A, for example. It can comprise so that a frictional force may be provided between (mounting surface).

  The fixing portion 131 fixes the position of the upper side holding member 130 with respect to the patient's wrist A. The fixing unit 141 fixes the position of the palm-side holding member 140 with respect to the patient's wrist A. Each fixing | fixed part 131,141 can be comprised by the hook_and_loop | surface fastener which can adjust a fixing position, for example. The fixing portions 131 and 141 are disposed at both end portions of the holding portion 120, and the upper side holding member 130 and the palm side holding member 140 are fixed in an annular shape by joining the both end portions.

  In addition, each fixing | fixed part 131,141 will not be specifically limited if it has the structure which can be fixed in the state which wound the holding | maintenance part 120 around the hand H, For example, a snap, a button, a clip, or a holding | maintenance part The frame member etc. which let the edge part of 120 pass may be sufficient.

  The constituent material of the holding part 120 is not particularly limited as long as it is a flexible material. Examples of such materials include polyvinyl chloride, polyethylene, polypropylene, polybutadiene, polyolefins such as ethylene-vinyl acetate copolymer (EVA), polyesters such as polyethylene terephthalate (PET), and polybutylene terephthalate (PBT). And various thermoplastic elastomers such as polyvinylidene chloride, silicone, polyurethane, polyamide, polyamide elastomer, polyurethane elastomer, and polyester elastomer, or any combination thereof (blend resin, polymer alloy, laminate, etc.). In addition, it is desirable that the inner surface of the holding unit 120 be provided with a material that provides a high frictional force with the mounting surface such as silicone rubber.

(Connection member 160)
The connection member 160 causes the patient's hand H to approach or separate from the patient's wrist A based on the distance between the mounting position where the mounting part 110 is mounted and the holding position where the holding part 120 is held. The mounting part 110 and the holding part 120 are connected to each other.

  The connecting member 160 includes a plurality of linear members 171a to 171d and a plurality of linear members 181a to 181d. As will be described later, each of the linear members 171a to 171d and each of the linear members 181a to 181d is a bending mechanism that generates tension to move the patient's fingers F1 to F4 so as to approach or separate from the patient's wrist A. It has a function. In addition, it is preferable to form each linear member 171a-171d and each linear member 181a-181d with a member with a comparatively thin diameter. Thereby, even when the connecting member 160 is individually arranged on each finger F1 to F4, the linear members 171a to 171d and the linear members 181a to 181d can be prevented from interfering with each other.

  As shown in FIG. 1, the upper side connecting member 170 includes a first linear member 171a that connects a portion corresponding to the tip of the little finger F1 of the mounting portion 110 and the upper side holding member 130, and a ring finger F2 of the mounting portion 110. A second linear member 171b that connects the portion corresponding to the distal end of the arm and the upper side holding member 130, and a third linear shape that connects the portion corresponding to the distal end of the middle finger F3 of the mounting portion 110 and the upper side holding member 130. It has the member 171c and the 4th linear member 171d which connects the part corresponding to the front-end | tip of the index finger F4 of the mounting part 110, and the back side holding member 130. FIG.

  As shown in FIG. 2, the palm-side connecting member 180 includes a first linear member 181 a that connects a portion corresponding to the tip of the little finger F <b> 1 of the mounting portion 110 and the palm-side holding member 140, and a ring finger F <b> 2 of the mounting portion 110. A second linear member 181b that connects the portion corresponding to the tip of the palm and the palm-side holding member 140, and a third linear shape that connects the portion corresponding to the tip of the middle finger F3 of the mounting portion 110 and the palm-side holding member 140. A member 181c and a fourth linear member 181d that connects the portion corresponding to the tip of the index finger F4 of the mounting portion 110 and the palm-side holding member 140 are provided.

  As shown in FIG. 1 and FIG. 2, the connecting member 160 includes a fingertip side connecting portion that connects the portions corresponding to the tips of the fingers F <b> 1 to F <b> 4 of the mounting portion 110 with the linear members 171 a to 171 d and the linear members 181 a to 181 d. 161, a wrist side connecting portion 162 that connects the upper side holding member 130 and the linear members 171a to 171d, and a wrist side connecting portion 163 that connects the palm side holding member 140 and the linear members 181a to 181d. ing. In the present specification, a position where the fingertip side connecting portion 161 is arranged is defined as “a mounting position where the mounting portion 110 is mounted”. Further, the position where the wrist side coupling parts 162 and 163 are arranged is defined as “a holding position where the holding part 120 is held”.

  The distance between the mounting position and the holding position is determined based on the lengths of the linear members 171a to 171d and the linear members 181a to 181d. The medical device 100 moves the patient's fingers F1 to F4 so as to approach or separate from the patient's wrist A by keeping the distance between the mounting position and the holding position substantially constant.

  As a constituent material of each linear member 171a-171d and each linear member 181a-181d, the thread | yarn consisting of a fiber, a metal wire, etc. are mentioned, for example. From the viewpoint of keeping the distance between the mounting position and the holding position substantially constant, each of the linear members 171a to 171d and each of the linear members 181a to 181d has a length due to the tension when pulling the fingers F1 to F4 to the wrist A side. It is preferable to select a material having such a high rigidity that does not change.

  The fingertip side connecting portion 161 and the wrist side connecting portions 162 and 163 can be formed of a bonding member such as an adhesive. It is preferable that the type and amount of the joining member be appropriately selected according to the material and shape of the mounting portion 110, the holding portion 120, the linear members 171a to 171d, and the linear members 181a to 181d.

  As shown in FIGS. 3A and 3B, when the operator or the like moves the upper side holding member 130 relatively away from the mounting portion 110, the upper side connection member 170 causes the mounting portion 110 to move the patient's side of the patient. A tension T1 is generated in a direction to approach the wrist A side. At this time, the instep side connecting member 170 brings the patient's fingers F1 to F4 closer to the patient's wrist A side by the tension T1. Thereby, a patient's finger | toe F1-F4 can be made into the state which curved the back of the hand Hb side.

  Also, as shown in FIG. 3 (B), the patient's fingers F1 to F4 are warped to the back of the hand Hb side, so that the medical device 200 such as an introducer or the like as the patient bends the hand H during the procedure. Can be prevented from being damaged due to kink.

  As shown in FIGS. 4A and 4B, when an operator or the like moves the palm-side holding member 140 relatively away from the mounting portion 110, the palm-side connecting member 180 causes the mounting portion 110 to move away from the patient. A tension T2 is generated in a direction to approach the wrist A side. The palm-side connecting member 180 brings the patient's fingers F1 to F4 closer to the wrist A side from the palm Hp side by the tension T2. Thereby, a patient's fingers F1-F4 can be made into the state bent to the palm Hp side.

  Further, as shown in FIG. 4B, the radial artery Tr can be raised on the back Hb side of the hand H by bending the patient's fingers F1 to F4 to the palm Hp side. Accordingly, since the operator can easily recognize the puncture site t1, it is possible to smoothly puncture the radial artery Tr with a puncture needle (not shown) for introducing the medical device 200. Specifically, adjustment is performed by pulling the linear members 171a to 171d and 181a to 181d on the palm Hp side and the upper Hb side, and the state shown in FIG. 4B can be maintained. Moreover, it is also possible to maintain the state of FIG. 4 (B) by arrange | positioning the leaf | plate spring which maintains the state of FIG. 4 (A) in the glove 101. FIG. In addition, the surgeon or the like can make the meandering radial artery Tr almost straight by bending the patient's fingers F1 to F4 to the palm Hp side. Thereby, an operator or the like can easily introduce the sheath tube or the like of the medical device 200 into the radial artery Tr. Furthermore, an operator or the like can smoothly deliver a guide wire, a treatment device, or the like to a desired lesion site via the medical device 200.

  In order to maintain the patient's hand H in a semi-grip state, for example, the back side connecting member 170 is pulled and balanced on the back Hb side of the hand and the palm Hp side by the palm side connecting member 180 and fixed. Or the medical instrument 100 is configured so that the hand H is always warped (the state shown in FIG. 4A) in a state where a leaf spring or the like is put in the covering portion 190 and no external force is applied. Also good.

  Further, the holding unit 120 is in a state in which the hand H in FIG. 3A is opened, in a state in which the fingers F1 to F4 in FIG. 3B are warped to the back Hb side, and in FIG. The shape of the patient's hand H can be held in a state bent to the Hp side. This eliminates the need to operate the hand H so that the patient himself holds the shape of the hand H. It is possible to prevent the medical device 200 such as an introducer from being damaged by kinking or the like due to the patient inadvertently moving the hand H during the procedure.
